COMS 4701 FINAL PRACTICE EXAM SPRING 2024 1.Consider a second-order hidden Markov model, in which Xt generally depends on both Xt-1 and Xt-2.The initial distribution is Pr(Xo,X₁),transition probabilities are Pr(Xt|Xt-1,Xt-2)for t≥2, and observation probabilities are Pr(E|Xt)for t≥1. (a)Circle either true or false for each of the conditional independence statements below that are guaranteed to hold in the second-order HMM. (b) Give a minimal expression for Pr(X₁,…,X₅,e₁,…,e₅) using […]
